Knowledge

The definition

What a system currently takes to be true: facts with a validity and a source, as distinct from the records they came from. A memory is a record of what was said; knowledge is the maintained answer to what holds. Two memories can disagree; knowledge has to decide.

The same words the glossary hub and the public data mirror carry; this page is the stable address for the term.

• Zep · ActiveEnterprise context infrastructure (temporal context graphs). Zep now describes itself as “the unified context layer for enterprise data”: its Context Lake unifies business data, documents and conversations into context graphs for agents. Its use of “context layer” overlaps with this site's vocabulary; the term is Zep's own and implies no affiliation. Zep's Community Edition is deprecated; the open-source Graphiti framework (Apache-2.0) is the self-hosted option. Its January 2025 paper remains a public, technical account of a temporal knowledge-graph approach to agent memory, evaluated on DMR and LongMemEval.
